get_ddr_munit(9)

💅 get_ddr_munit(9) — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual ✨ this one's about get_ddr_munit, and honestly? it's a little sleeper hit. no cap.

---

🌸 NAME

get_ddr_munit — grab the resource of the i-th DDR memory controller. that's it. that's the whole job. she's focused, she's iconic 🎀

---

🦋 SYNOPSIS

struct pci_dev * get_ddr_munit (struct skx_dev *d , int i , u32 *offset
, unsigned long *size );

literally just look at her go 💫

---

💖 ARGUMENTS

• d — the pointer to the structure of the CPU socket EDAC device. like, the whole socket's main character energy 👑
• i — the index of the CPU socket–relative DDR memory controller. which one are we talking about? this one. numbering starts from the socket, iykyk.
• offset — where you store the MMIO offset of the i-th DDR memory controller. that's her little output slot 🫶
• size — where you store the MMIO size of the i-th DDR memory controller. also an output, also important, don't forget her 💜

---

🔥 RETURN

the PCI device of the i-th DDR memory controller on success. and if it goes wrong? NULL on failure 😭 no device, no drama, just NULL. check it, bestie.

💀 friendly reminder: offset and size are outputs — you're writing into them, not reading. don't get it twisted 🙈

okay that's the whole page, you ate that 🍓 so anyway this lil baby lives over in ./drivers/edac and the manual's dated October 2026 — mwah, periodt 💅🧚‍♀️
